A review of the device history records was performed for the indicated packaging and component lots for any deviations related to the reported defect of the complaint.The review confirms that the lots met all material, assembly and performance specifications.The recent angiodynamics complaint report was reviewed for the vortex port product family and the failure mode "catheter fractured." no adverse trend was identified.Returned for evaluation was one vortex port with catheter tubing.As reviewed, the port catheter tubing was fractured between the 10 and 11 cm mark and sliced between the 11 and 12 cm mark.The blue boot was attached to the port stem with the catheter extending out 9 cm.The catheter was connected to the port at the 20 cm mark, and it appeared to have been trimmed to 20 cm.At the catheter fracture site it appeared squashed and oval like it was pinched off.The catheter was measured (id and od) and found to be within specification.The reported complaint description is confirmed for catheter tubing fracture between the 10 and 11 cm mark.Although no definite root cause could be identified, the catheter broke about 9 cm away from the port.The oval/crushed appearance of the fracture suggests it was a pinched, flex failure.The rest of the catheter was found to be normal in appearance and measured within specification.Based on the location of the fracture from the port body and the fracture appearance, the likely root cause of the failure is "pinch-off" syndrome.Angiodynamics' incoming inspection for the catheter tubing include visual inspection for damage or defects, untimate tensile force verification and od/id verification.The directions for use provided with the port contain reference to the potential complication of pinch-off-syndrome including guidance on port placement to avoid this condition and symptoms after placement which could indicate pinch-off-syndrome.(b)(4).
